Custom fields in events

Custom fields in events

Hi,

I'm interested in using custom fields in Events. My use case is that we have multiple events a year (3 to 4), which are of different kinds. I like to "qualify" them by a "Kind of event" field, or by an event code.
Backstage events are synchronized with CRM, this custom field value would be copied in the Campaign Module. There, we can use this field for sorting, seraching etc... and also trigger workflows.

If no synchronization is possible, I could trigger zoho Flow to copy custom fields from Backstage to CRM.

How can I achieve this ? Is there may be an existing field I can use for my use base ?

Regards,
